We were observing the lunar eclipse. Shortly after 2200, I saw an object that was round to oval in shape I am unsure if it was tilted if at all. It was not emitting any light at first but a faint reflection of light pollution making its shape apparent. I was facing east; it passed by at about 20-30 degrees above the horizon moving from south to north. I noticed it first coming into sight from the right behind a few trees. It was in plane sight for approximately 90-120 degrees, for 5- 10 seconds. For the last 3 seconds of my observation, it was emitting a neon-blue light. There was no apparent source of the light, meaning no visible bulb or bulbs, it looked like it was projected off of the surface or the surface itself was emitting the light in sporadic pulse. Only parts of it were making light, not the whole object, it was not in unison or uniform. It was like an imitation of lightening or the reaction to some form of stimulation, comparable to bio-lumination. It stopped making the blue light just before it fell out of sight behind more trees. It did not slow, stop, accelerate, or alter course for the duration of my observation. I am within 5 miles of a municipal airport, and within 10 miles of a naval station, that holds near constant helicopter operations, this was not a helicopter, I have military training in identifying and reporting surface and air “contacts” and identifying standard light configurations, I am very familiar with the helicopters I used to observe in the military and watch fly over the house every day and all hours of the night. It did not make a sound. I can only speculate the altitude of the object; it was low enough to reflect a very faint and dull light from urban lumination for the duration of my observation.
